Abstract: 801,688. Valve circuits for radio reception. FERRANTI, Ltd. Nov. 7, 1956 [Aug. 20, 1955], No. 24049/55. Class 40 (5). In a superheterodyne television receiver in which a video I.F. stage is designed to reject sound I.F. carrier, means are provided to derive from a subsequent stage a signal at the beat frequency of sound and vision carriers which is used to indicate correct tuning. The screen-grid circuit of a video-frequency amplifier 21 includes a circuit 27 tuned to the beat frequency and feeds a diode rectifier 31. This is coupled to the sound-channel A.V.C. line 35 via a series diode 35. The arrangement is such that when the receiver is in tune, the sound I.F. carrier is rejected in the video I.F. amplifier and consequently no voltage appears across circuit 27; when off-tune, however, both video and sound I.F. carriers reach the video detector and the beat frequency appears across circuit 27, is rectified by diode 31 and the resultant negative potential across load resistor 32 is applied via diode 33 to the sound A.V.C. line, causing a drop in sound output. In another embodiment, Fig. 5 (not shown), the diode 31 is reversed and feeds a tuning indicator tube. The potential on the sound A.V.C. line is also applied to the tube in order to give an indication of the absence of a signal.
